Compact hot air hand tool WELDPLAST 300

Overview
The WELDPLAST 300 extrusion welder from Leister is a compact, hand-operated extruder for professional welding of PE and PP. Intended for equipment, vessel and membrane fabrication, it delivers high material output with precise process control and low operating costs.

Key benefits

• Up to 40% lower welding costs
• Brushless motors for reduced maintenance and extended runtime
• Eco Mode reduces energy consumption by up to 60%
• Consistent weld quality with voltage variation tolerance of ±20%
• Dual Heater (2-zone screw heating) reduces risk of rework

Detailed description
The hand-operated extruder provides high output while ensuring ergonomic handling and accurate process control. POWERdrive and ECOdrive technology on the brushless drive and blower motors increase runtime and reduce wear. Closed-loop air temperature control and LQS (Leister Quality System) enable process documentation. The design allows multiple hand positions, a side-mountable rest stand and optimized cable routing for on-site work.

Highlights

• Brushless technology for lower maintenance and longer uptime
• Dual Heater (DSH) for accurate temperature control and uniform welds
• Ergonomic design for comfortable handling and varied working positions
• LED work light for improved visibility
